The light source 110, the pivot member is driven to rotate by a flat motor, the flat motor includes a stator 400 that is energized to generate a magnetic field, and a rotor 500 sleeved outside the stator 400 and driven by the magnetic field, the pivot member and the The rotor 500 is fixedly connected, the support member is fixedly connected to the stator 400 , or the pivot member is fixedly connected to the stator 400 , and the support member is fixedly connected to the rotor 500 .
所述高精度旋转定位的舞台灯,利用定子400上交替变换的磁场驱动所述转子500旋转,所述转子500由于是套设在所述定子400外的,端面面积相对于传统的转轴电机的转轴更大,更易于与所述枢接件或者支撑件相固定,也不会随便发生晃动,稳定性更好。而且由于取消了传动组件,避免了机械传动过程中由于精度等问题出现的传动误差,从而可以对所述枢接件的定位更加准确,即使远距离投射,光斑也不会发生偏移。另外,直接将所述定子400或者所述转子500与所述枢接件连接,所述定子400或者所述转子500可以作为所述枢接件的枢接轴,无需额外设置空间用于安装电机,解决了之前由于电机存在而需要将机箱300或者支撑臂200设计的较厚的问题。并且,将转子500套设在定子400外,相对于传统的转轴电机,取消了转轴,从而实现电机高度的降低,便于电机安装在高度有限的空间位置。The high-precision rotary positioning stage light uses the alternating magnetic field on the stator 400 to drive the rotor 500 to rotate. Since the rotor 500 is sleeved outside the stator 400, the end surface area is relative to the traditional shaft motor.
